I hunt in an area now where the deer psm is below one and I fill my tag nearly every year. Now consider that half of the deer I am hunting are does and I can only shoot bucks, I am now hunting a deer population that is near .30 deer psm.
Did you post that as a joke or were you serious? Unless you only hunt cornfields for deer I doubt here are any huntable areas in PA with less than 5 DPSM. Or are you talking about hunting in maine?
